🚀 Winner of Tron Grand Hackathon 2022 (Web3 track 5th place): 4thTech's HolaChain, Web3 Secured W2W dMail & dChat Communication Infrastructure 🚀

4thTech's | Solutions Ecosystem

Not only an end-user dMail & dChat UI dApp, but a permissionless multi-chain communication standard that enables 1000s of dMail & dChat dApps Blum on Web3, via SDKs & White-labels, while it's core Web3 primitive; one message = one L1 transaction, utilises L1s security to enable immutable W2W on-chain communication

FOURid | dID

Connects wallets when messaging data is exchanged and serves as the public key exchange point between users, while it can provide wallet address verification by creating a link between an X.509 user’s online identity and blockchain wallet address

FOURdx | W2W E2EE dMail

FOURdx protocol enables W2W dMail communication & data file exchange accompanied by on-chain dNotary & proof of delivery. With its core Web3 primitive in place; one message = one L1 transaction, the unique protocol architecture utilises L1s security with decentralized storage to enable true private & immutable W2W on-chain communication

Web3 Security & Data ownership


FOURdx | 20+ Chain Support
As a multi-chain EVM, Substrate & Solana framework, the FOURdx protocol enables the dMail interoperability with Ethereum, Edgeware, Moonbeam, Solana, Tron & Evmos chains. The dMail will be available on 20+ chains creating the foundation for the first Web3 W2W communication standard

FOURdx | Not Your Keys, Not Your Data
Every wallet becomes an on-chain identity & message data vault, accessible only with users' private keys! The protocol uses an advanced encryption standard (i.e., AES), with a combination of RSA encryption and hash algorithm 256 (i.e., SHA 256) to secure immutable W2W E2EE dMail & data file exchange

4thTech dMail
FOURdx | One dMail = One L1 Transaction
Compared to dChat, where W2W message exchange happens on-chain, the dMail is data heavier due to attachments and sizable content. The key was combining L1 security with decentralized storage where lite encrypted JSON files are stored to hold dMail metadata while link to dMail JSON metadata and checksum are recorded on-chain in the form of a L1 transaction

FOURim | W2W E2EE dChat

Lightweight architecture keeps all communication on-chain, while only users can access their messaging data by their private keys. The protocol enables W2W E2EE on-chain chat & NFT curated chat groups safeguarded by L1s security

FOURns | On-chain Data Verification

Uses checksum to check for potential data changes during the W2W dMail data exchange and acts as the digital notary of the decentralized world enables sensitive data files time-stamp and origin verification using blockchain as a "trust" source
FOURid icon
Checksum Validation =
calculating checksum of stored JSON metadata file & digital file(s) and comparing the result with saved values
Tracking Files
Timestamping digital data files via FOURns system & file checksum verification
Verifying Data Authenticity
If one byte of the exchanged data is modified, the checksum changes and invalidates the transmission
Simple Solution GUI
